Weight Gain: Causes and Contributing Factors

Weight gain is often more than just a result of overeating or lack of exercise. It can be a symptom of a variety of underlying health conditions and factors, each contributing in different ways. Understanding these causes is crucial for accurate diagnosis and effective treatment, and ICD-10 coding helps in identifying the root cause of a patient’s weight gain.

Metabolic and Hormonal Conditions

One of the most common causes of unexplained weight gain is metabolic or hormonal imbalances. Conditions like hypothyroidism (underactive thyroid) can slow down metabolism, leading to weight gain. Similarly, polycystic ovary syndrome (PCOS) can affect hormonal levels, causing weight retention, particularly around the abdomen. Cushing’s Syndrome, a disorder caused by excess cortisol, can also lead to significant weight gain, especially in the face and upper body.

Medications and Treatments

Certain medications can cause weight gain as a side effect. For example, antidepressants, antipsychotics, and corticosteroids have all been linked to increased weight. This is particularly relevant for healthcare providers when coding weight gain related to medication. Using the correct ICD-10 codes helps to distinguish between weight gain caused by an underlying condition versus medication side effects.

Lifestyle Factors

While medical conditions contribute to weight gain, lifestyle factors like diet and physical activity are often at play. A sedentary lifestyle combined with poor eating habits can lead to gradual weight gain over time. Psychological factors such as stress and emotional eating can also contribute significantly.

Identifying these factors with the help of ICD-10 codes ensures a comprehensive approach to diagnosis and treatment.
